I have 3 printers with the exact same issue.
When I print more than 3 pages from Tray 3 I get 3 pages a blank page then motor/fan noise like it is trying to do something. The only fix is to shut it down and print 3 pages at a time.
I have tried printing from different workstations OS's even switched out the network cable and tried a different port on the switch.
I have changed out network cards (610 & 620), updated firmware, tried UniversalPCL6 & PCL5 drivers
Tried printing as network printer & local printer.
Changed out all rollers.
Used different types of paper
Always the same result.
One printer jams 13.20 and 13.10 in event log (this might be sensor PS102 but haven't had time to take a look yet). But it jams on the 3rd page and when I unjam it just prints out the 4th blank page and stops goes to ready no noise?)
Has anyone run into this...
